MPLAB ® ICD 3 In-Circuit Debugger User’s Guide5.6 VIEWING DEBUG OPTIONSBefore you begin debugging your code, review the default settings of several items. Inyour own projects, you may need to set these items differently.5.6.1 Configuration BitsIn this tutorial, the relevant device Configuration bits are set in the counter.c codeusing the _CONFIG1 and _CONFIG2 directives. For information on the function of thesePIC24FJ128GA010 configuration register bits, see the “PIC24FJ128GA Family DataSheet” (DS39747).Configuration bits also may be set by selecting Configure>Configuration Bits andunchecking “Configuration bits set in code”. Do not change any values for this tutorial.FIGURE 5-6:CONFIGURATION BITS WINDOW5.6.2 Selecting the Debugger as a DebuggerTo select MPLAB ICD 3 in-circuit debugger as a debugger, select Debugger>SelectTool>ICD 3. Then:1. The Output window will open to display connection information. Depending onthe version of MPLAB IDE or the device selected, a message box may appearindicating that the firmware needs to be updated. Select OK in the message boxto allow MPLAB IDE to install the new firmware. Also, since different MPLAB ICD3 firmware is used for different families of devices, this message box may appearwhen switching to a different device.2. The Output window will display information about the firmware update and willshen when the MPLAB ICD 3 is connected to the target.3. The Debugger menu will show available debugger debug options.4. A Debug toolbar will appear. Mouse over a button to see a pop-up of its function.5.6.3 Programming OptionsTo set program options, select Debugger>Settings and click on the Program Memorytab.DS51766A-page 36© 2008 Microchip Technology Inc.
TutorialFIGURE 5-7:DEBUGGER PROGRAM MEMORY TAB5.7 CREATING A HEX FILEHere you may allow the debugger to automatically choose the programming ranges(recommended) or you may select ranges manually.• The “Memories” section should have “Program” checked, and “EEPROM” and“ID” unchecked. When using the MPLAB ICD 3 in-circuit debugger as a debugger,Configuration bits will always be programmed and the “Configuration” box will bechecked and grayed out.• For the PIC24FJ devices, all memory will be erased each time the chip isprogrammed. Therefore, in the “Program Options” section, “Erase all beforeProgram” will have no effect.• The “Program Memory” addresses (“Start” and “End” address) set the range ofprogram memory that will be read, programmed or verified.When debugging code, you will frequently repeat the edit, rebuild, reprogram and runsequence. To automate this, there are checkboxes “Program after successful build”and “Run after successful program”. Leave these unchecked for now.To create a hex file for debugging:• On the Project toolbar, select “Debug” from the Build Configuration drop-down list.• Select Project>Build All or right click on the project name in the project windowand select “Build All” from the popup menu.The project will build (Figure 5-8), and the resulting .hex file will have the same nameas the project (Figure 5-9). The hex file is the code that will be programmed into thetarget device.Note:Depending on the build options selected, your Output window may lookdifferent from Figure 5-8 (Project>Build Options>Project, MPLAB C30 andMPLAB LINK30 tabs.)© 2008 Microchip Technology Inc.
